Fisher™ Dirty Service Trim – Robust Control Valve Trim for Abrasive & Slurry Applications

Product Overview

The Fisher™ Dirty Service Trim is a highly durable valve trim specifically engineered to handle the most challenging flow control applications involving abrasive slurries, dirty fluids, and process streams containing solids. In industries like mining, wastewater treatment, and hydrocarbon processing, standard valve trims can quickly fail due to clogging, erosion, and material degradation. This robust trim solution addresses these issues head-on with its innovative design, which features large, open flow passages and hardened materials to resist wear and prevent particle accumulation. By ensuring reliable operation and extending service life in severe conditions, the Fisher Dirty Service Trim helps minimize maintenance downtime and reduces the total cost of ownership for your most demanding flow control assets.

Key Features & Benefits

• Superior Abrasion Resistance: Constructed from hardened materials that provide exceptional resistance to wear from solid particles suspended in the fluid, significantly extending the trim’s operational life.

• Clog-Resistant Design: The engineered flow paths and large passageways are designed to prevent the buildup of solids, ensuring consistent operation and reducing the frequency of maintenance cleanouts.

• Enhanced Service Life: By mitigating the primary failure modes of erosion and clogging, this trim dramatically increases the lifespan of both the trim and the valve itself, delivering a better return on investment.

• Reliable Performance in Severe Service: Built to maintain stable control and reliable shut-off in applications that would rapidly degrade standard valve trims, providing operational continuity.

• Reduced Maintenance Costs: The durable design and clog-resistant nature lead to fewer maintenance interventions, lower parts replacement costs, and less process downtime.

Typical Applications

• Mining & Mineral Processing: Tailings lines, thickener underflows, and slurry transport.

• Wastewater Treatment: Sludge control, grit removal, and recirculation lines.

• Power Generation: Fly ash and bottom ash handling systems.

• Pulp & Paper: Stock and coating applications.

• Chemical Processing: Abrasive catalyst streams and effluent control.
